Transmission Throttle Cable Adjustment
Hello,
I just put in a transmission and want to adjust the throttle cable attached to the transmission. But I don't understand what it states in the FSM.
In the Lexus manual, it says to measure the distance between the outer cable and the stopper on the cable and have about a 0-1 mm slack. Could someone post a picture of how to do this. I don't know what they mean about the stopper and the outer cable. THe picture doesn't really show how to do this.
Your help would be greatly appreciated. Thanks.

Just wanted to bump this to share my discovery. I had transmission jerk from P to D as well as R. Also between all gears.
I first thought it was trans mount or oil. Changed those but no improvement.
Then I thought it could be the drive shaft bushing etc. But no...
It was this cable that was little too loose. Basically the transmission was thinking car was at lower RPM than it really was, resulting in the jerk. Took 5 minutes. I can barely feel it shifting now.
Very easy to do, as cation said above, there is a stopper on the cable and it should almost touch the cable outer. (<1mm)
This is a must do DIY i think...

Hi All, I'm bringing this back from the dead. I have the same problem with jerking when shifting from park. I followed the guide in the above link and my throttle cable seems to be different. The rubber stopper is stationary on the end and does not move. There is a metal ball or bulge (circled in red in first picture) that is on the cable that does not move. Anyone have any idea? I can pull the rubber stopper off. Here are a couple of pictures. The first one is how it looked "normally" when I pulled the plastic over off the throttle body, the second picture is when I move the rubber stopper. TIA for any help!

By the way, a mechanic just replaced the starter, that's why the transmission throttle cable is off, I just wanted to see if I can fix it before going back there.

I was in a rush sat morning, so I adujsted so that the metal bulge was to just the beginning of the rubber part, everything improved significantly. Now that I have seen the additional responses, I will tighten it up some more when I get back home today. Thanks all! I'll take some more pictures, so others who have questions or who aren't very mechanically incline such as myself can have a dummies guide hehe 
Thanks!
Thanks!

bringing up this dinosaur again, i adjusted the cable to what is needed however i can still feel the 1-2 shift, would i need a new mount in this case 
. Also the cable is seems a little loose the way it fits even though i have it where it should be.

Just did this. When I opened my hood I found out the rubber hose was pulled about an inch. I put it back into metal tubing and no more jerking! Wow glad I didn't listen to mechanic yesterday about how my transmission is going bad. I went in to have tranny fluid drained/filled with toyota t-iv and he's telling me to just drive it til it fails and rebuild. It shifts like almost new again... Now odo is at 208K and I'm ready for another 200K miles!
